I want to use media sale themes, plugins and extensions from Graph Paper Press (http://graphpaperpress.com/downloads/category/extensions/)

to create a uniquely simple to use, highly professional royalty-free media selling website incorporating the full features provided by the theme developer.
see http://graphpaperpress.com/plugins/sell-media/

The example of a website closest to my target in terms of functionality and structure is 123rf.com. The target is more or less a market place for contributors from all over serving online royalty photo and media clients.

I will provide the full package (Theme, extensions, and Plugins) from graphpaperpress but will also need to use other WP plugins or custom solution for such things as:

a) Live Chat Customer Support and Ticket Management

b) SMS integration for User verification with One Time Password (OTP)

Very important to me:

1) Top top quality graphic design / color combination skills

2) Smooth Functionality and ease of use…so simple for even a child to navigate

I have a limited budget for the customization but will not compromise on the two points above, and need your best quote and duration estimate.

The project is planned to be awarded to a competent expert within the next 7 days so a quick and precise response from experts in WordPress and Woocommerce will be appreciated.

NOTE: I am looking for a hands-on guys/team and not an agent or middleman. Please note agents or Middlemen will NOT be considered for this particular job.
